CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent N0. 788,555, dated May 2, 1905. Application filed July 7,1902. Renewed March 28,1905. Serial No. 252,530.

cient automatic means whereby the wool or other stock or material from the primary.

carding-machine, no matter whether of low or high grade, may be doubled or mixed and conveyed directly, if preferable, to the finishing-machine," and thereby effect a saving in material or stock and a saving of time and produce a yarn of better quality than has been produced in machines of this class as at present constructed.

A subsidiary object is to keep the fiber straight as it passes from one machine into the other, so that the fibers are fed endwise and not broken or disturbed and the bat is fed in doubled or crimped form.

The invention consists, essentially, of a doubling or mixing roller connected to the discharge end of the primary machine, such roller being arranged to come in contact with the doffer-roller, a vibrating comb suitably driven and designed to coact with the mixingroller, a conveyer having one end near the doffer and mixing roller and having its opposite end extending into proximity with the feed-roller of the finishing-machine, a compressor-bar suitably operated in proximity with the feed-roller of the feeding-machine, a licker-in roller located substantially above the uppermost feed-roller and coacting therewith, and a lu'mper-roller located substantially above the licker-in roller, the parts being arranged and constructed as here nafter more particularly explained.

The evener-arms N are formed in two portions n n, provided, respectively, with the vertical and longitudinal slots n 11?. The portion n is secured by a bolt a, passing through vertical slot into the bearing of the mixing-roller. The portion n is secured to the portion n by a bolt n", passing through the longitudinal slot a into the portion n.

D is an extension-piece secured at right angles to the extension-arm d and provided with a slotted portion (i in which the cam d is designed to operate. b

As the worm-gear revolves it rotates the worm-wheel, and the cam carried thereby revolves in the slot, and thereby carries the spindle longitudinally in its bearings, imparting a reciprocating movement thereto.

Having described the principal parts involved in my invention, I will briefly describe the operation of the same.

The wool passes beneath the doifer-roller in the form of a fleece and is caught by the mixing-roller, which oscillates, as hereinafter described, thereby evenly spreading the wool against the evener-arm, so as to make the bat of uniform width. The wool then falls onto the conveyer in the form of a carded fleece. The conveyer is driven at a very low rate of speed, preferably in proportion of one inch of travel to one hundred inches of travel of the mixing-roller. By this means the fleece is gathered or crimped together in the form of a continuous bat, as shown in Fig. 3, with its fibers perfectly mixed. The beater-rod M insures the bat being even in width before it passes between the feed-rollers by forcing it outwardly against the eveners. If there are any lumps or inequality of thickness in the bat, they are removed by the lumper-roller, which picks up the lump and carries it back to the wiper-roller. The adjacent peripheries of the lumper and licker-in rollers rotate in the same direction, and the adjacent peripheries of the lumper and wiper rollers rotate in the opposite direction, while the adjacent peripheries of the wiper and licker-in rollers rotate in the same direction. Thus the lump is picked from the fleece by the lumper-roller, which carries it around to the wiper-roller, which tears the lump therefrom, so as to pull the lump apart, and then the wiper-roller carries it back into the fleece at the periphery of the licker-in roller, thus insuring the bat passing in a perfectly even state into roving. It will be seen from this description that the wool is fed forward automatically from the primary cardingma chine into the finishing machine, with its fibers always moving in the same longitudinal direction in relation to each other, so that the fibers are kept in a longitudinal form parallel to each other, are crimped together as it passes over the apron by reason of the difference in the rate of movement of the apron or conveyer and the mixing roller, thereby thoroughly mixing the fibers longitudinally, and thus the wool is carried forwardly in an unbroken continuous bat into the finishingmachine.

B m method very short fibers may be used an fed directly in parallel relation and evenly to the finishingmachine, thereby producing a much stronger roving in a minimum space of time out of an inferior quality of fleece.
